UNITED STATES ANTHONY VANDERVELD, OF GRAND RAPIDS, MICHIGAN.

PRESSER-ROLLER CONSTRUCTION.

Application filed October 13, 1921, Serial To GUM/1072b it may concern:

Be it known that I, ANTHONY VANDnR- vunn, a citizen of the United Statesof America, residing at- Grand Rapids, in the county of Kent and Stateof Michigan, have invented certain new and useful Improvements inPresser-Roller Constructions; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenableothers skilled in the art to which it appertains to make and usethe same.

This invention relates to improvements in measuring machines in which ameasuring roller is operated by frictional engagen'ient of a length ofcloth or like material drawn between the measuring roller and a presserroller which presses the cloth against the measuring roller to insureproper contact therewith for its sure and positive actuation. Thepresent invention is concerned primarily with novel constructionspertaining to the presser roller which is located un der the measuringroller and over which the length of cloth, ribbon or the like is drawn,

as fully disclosed in my Patent No. 1,420,612,

granted June 20, 1922, for measuring and. computing machine.

hen the cloth or ribbon is drawn over the presser roller it is notunusual for threads to separate from the same at its edges, or lint tobe given off therefrom which, unless provision is made therefor, willget between the roller and the shaft or journals on which it is mounted,thereby clogging the movement thereof with a resultant interference withthe effective op eration of the machine. It is a primary purpose of theinvention to provide a novel construction and mounting of presserroller, and equip the same with guards at its ends which will. insureagainst the possibility lhat the presser roller shall be thus cloggedand. stopped from movement, the presser roller at all times being freelyrotatable irrespective of how much or little lint, threads, or the likeis gathered from the cloth or ribbon on and around the guarding means atthe ends of the presser roller.

F or an understanding of the invention and the mechanisms embodying thesame, reference may be had to the following description, taken inconnection with the accompanying drawing, in which,

Fi 1 is afragmentary front elevation No. 507,525. Renewed December 4,1924.

and vertical section through the lower part of a machine. equipped withmy invention, the section being taken on the plane of line 1--1, of Fig.2, and

Fig.2 is a fragmentary horizontal section taken on line 22, of Fig. 1.

Like reference characters refer to like parts in the different figuresof the drawing.

The measuring and computing machine includes an outer housing or casingwithin which the mechanism is enclosed. This housing is mounted on andabove a base 1, and is indicated at 2, at its front end being located adistance over the base and leaving a space in, which a table member maybe placed and secured. The table member comprises an upper horizontalplate 3 from which at its front and side edges integral dependingflanges 4t extend to the base, as shown. The plate 3 has an elongatedopening 5 therein directly below the measuring ,roller 6 and throughwhich the presser roller passes to either bear against the measuringroller or against the cloth run between the two rollers.

Supporting arms 7 and 8 within the table member are provided to carry arod 9 on which a sleeve 10 is mounted from which at its inner end an arm11 extends to a point under the opening 5. The opposite end of thesleeve is enlarged into a head 10 and a similar arm 12 secured theretoby screws, the same paralleling arm 11. The ends of the arms 11 and 12terminate in heads 13 which are turned in toward each other and whichare progressivelyenlarged from their juncture with the arms to theirends where they terminate in flanges 14:, as shown, the heads on theirouter surfaces being substantially bell-shaped. A red 15 is disposedhorizontally between the two heads and carri id thereby, the head on arm12 being connected to the end of the rod in an y suitable manner afterassembly of the roller con structi on on the rod.

An elongated sleeve 16 threaded at both ends is loosely mounted on rod15 between the heads 13 and on each end of the sleeve a member isattached, comprising a neck 17 interiorly threaded to engage with thethreaded end of sleeve 16, and an enlarged cup-like portion 18 intowhich the heads 13 and flanges 14 thereof may extend. The presser roller19 of rubber or rubber-like material is mounted on the sleeve 16 beinging one end bearing against the base 1,, and.

the other end L0 hooked over an arm 21 integralwith and pro ectnigd rOmthe sleeve v 10. The end of the lever 22 for operatmg the ln'esserrolleraway from themeasuring 21. This construction is fullypshown in roller isshown as extending under the arm my prior application towhich referencehas. been made, and need not be further described, it forming no partof; the present invention.

the ends of the roller. serve asefl'ective guards against the entranceof threads or lint and the rotation of the roller will wind the samearound the bellshaped guard heads 13 where they are harmless tointertere with the rotative movement of; the

roller. Otcourse, in time the. table memberv will have to be removed andthe lint and;

threads cleaned out andremoved, thisbeing necessary, however, in anycase. But no in terterence with the free turning movement of the presserroller can occur. The construction is practical, easily andeconornically made and durable and has so proved inpractice. I claim 1.In a construction of the class described, two spaced apart supportingarms, each terminating in a bell-shaped head, said heads being turned intoward each other from the ends of the arms, a rod located between andcarried at its endsby said heads, a sleeve mounted on the rod andextending between the heads, two cup-like members secured one at eachend of the sleeve, and a roller located around the sleeve between saidmembers,

said roller at its ends having recesses into which said members areinserted and said heads extending into the said members, sub stantiallyas described.

2. In a construction of the character described, two spaced apartsupporting arms, each terminating in a bell-shaped head, sald headsbeing turned inwardly toward each other and progressively enlarging fromthe ends of the arms, arod disposed between and supported at its ends bysaid heads, a sleeve threaded at both ends mounted on the rod andextending from one head to the other, a member having an interiorlythreaded neck and an enlarged cup-like portion threaded on to each endof the sleeve, and a roller, located around the sleeve and between saidmembers, said roller having recesses at its ends for the reception ofsaid members, and the enlarged portions of the heads enitering thecup-like portions of said members,.substantially as described. V Intestimony whereof I aflix my signature.

ANTHONY VANDERVELD.
